Unit 6: State Modelling
Notes
!
Caution It is possible to define any number of actions of each type.
Self-transitions: A state can have a transition that returns to itself as shown in the Figure 6.6.
This is the most useful when an effect is associated with the transition.

Compound States: Substates may be nested to any level.
Example: In figure 6.7, we have shown that a state machine diagram may include
sub-machine diagrams.

There is also an alternative way of showing the same information.
